Using SOLIDWORKS Direct Modeling to modify an imported model without feature history [VIDEO]

Direct Modeling

How can you modify a model without history? Use the SOLIDWORKS direct modeling tools to reverse engineer an existing model. When you need to create tooling or fixtures for your customer parts, it is often necessary to remove all the details that will not be produced by your tooling, or features which are simply not required for modeling your fixture. This process becomes more complicated when the model you receive from your customer has been created with different CAD software. That means you will import only the geometry of the part, without the feature history that created it. Reverse engineer/model an imported part Trying to reverse engineer the part in order to discover how the model has been created is detective work. Less experienced SOLIDWORKS users will try to guess how the part looked early in the modeling process by adding or removing material, using features such as the Extrude-Boss or Extrude-Cut. This can be a very tedious process, with a…

How to Reduce the Number of Edges for an Imported Surface?

How many times have you imported a neutral format file (STEP, Parasolid, IGES) in SolidWorks and encountered challenges when working on it? Let me give you an example regarding edges: “How many open edges does the surface from fig. 1 have?”

SOLIDWORKS Extend Surface command does not work with my model?

You are a tool and die designer and your customer has just sent you an IGES file containing a solid with a complex face which has to be used as reference for your embossing die. In order to create your punch and die inserts, you need to isolate that surface and extend it. If you can do that, you will take the job, if not – you have to refuse it. You have no problem offsetting that face in order to create the surface body, but when you try to apply the Extend Surface command to the new surface, an error message pops up… You are right, the Extend Surface command does not work in this case. Fortunately, there is another command available in the Surface toolbar – Untrim Surface. With Untrim Surface, you can patch surface holes and external edges by extending an existing surface along its natural boundaries. You can…

Tool and Die – Emboss Punch Design Topic: When Extrude to Surface does not work…

As a former Tool and Die designer I came to appreciate the power of SolidWorks when designing Embossing Dies. Most of the times, I would use the face of the part sent by my customer for either “Extrude to Surface” or “Cut with Surface” commands as a reference in designing my embossing punches and die sections. There are situations when this approach does not work. One workaround, involving the “Thicken Cut” command is presented in this video (no audio provided):
